Walked back to the Sport in the Wallyworld parking lot yesterday and noticed a dark spot under the rear of the engine. Got it home and crawled under to check it out and it looks like the rear crank seal has sprung a leak. How much work is it to replace it? I have a feeling it is more of a task than I want to take on. The wallet is probably going to take a hit--I'll just have to tell the wife that we won't be eating out at McD's for a while.
